Hybrid automatic repeat request feedback for outer loop adaptation for 5g or other next generation network

ABSTRACT

Intelligent hybrid automatic repeat request (HARQ) feedback can better support link adaption. Thus, in addition to the traditional HARQ feedback, which is to relay acknowledgement (ACK) and negative acknowledgement (NAK) data based on a decoding result, a new state for the HARQ feedback can be represented as “ACK+”. Consequently, ACK+ can be used to indicate to the network that a modulation and coding scheme (MCS) of a current data packet is too conservative, and the user equipment (UE) is capable of supporting a more aggressive MCS.

BACKGROUND

5th generation (5G) wireless systems represent a next major phase ofmobile telecommunications standards beyond the currenttelecommunications standards of 4^(th) generation (4G). Rather thanfaster peak Internet connection speeds, 5G planning aims at highercapacity than current 4G, allowing a higher number of mobile broadbandusers per area unit, and allowing consumption of higher or unlimiteddata quantities. This would enable a large portion of the population tostream high-definition media many hours per day with their mobiledevices, when out of reach of wireless fidelity hotspots. 5G researchand development also aims at improved support of machine-to-machinecommunication, also known as the Internet of things, aiming at lowercost, lower battery consumption, and lower latency than 4G equipment.

The above-described background relating to a HARQ for an outer loopadaptation for new radio sidelink communication is merely intended toprovide a contextual overview of some current issues, and is notintended to be exhaustive.

Additionally, substantially allaspects disclosed herein can be exploited in legacy telecommunicationtechnologies.

Described herein are systems, methods, articles of manufacture, andother embodiments or implementations that can facilitate HARQ for anouter loop adaptation for new radio sidelink communication for a 5Gnetwork. Facilitating HARQ for an outer loop adaptation for new radiosidelink communication for a 5G network can be implemented in connectionwith any type of device with a connection to the communications network(e.g., a mobile handset, a computer, a handheld device, etc.) anyInternet of things (IOT) device (e.g., toaster, coffee maker, blinds,music players, speakers, etc.), and/or any connected vehicles (cars,airplanes, space rockets, and/or other at least partially automatedvehicles (e.g., drones)). In some embodiments the non-limiting term userequipment (UE) is used. It can refer to any type of wireless device thatcommunicates with a radio network node in a cellular or mobilecommunication system. Examples of UE are target device, device to device(D2D) UE, machine type UE or UE capable of machine to machine (M2M)communication, PDA, Tablet, mobile terminals, smart phone, laptopembedded equipped (LEE), laptop mounted equipment (LME), USB donglesetc. Note that the terms element, elements and antenna ports can beinterchangeably used but carry the same meaning in this disclosure. Theembodiments are applicable to single carrier as well as to multicarrier(MC) or carrier aggregation (CA) operation of the UE. The term carrieraggregation (CA) is also called (e.g. interchangeably called)“multi-carrier system”, “multi-cell operation”, “multi-carrieroperation”, “multi-carrier” transmission and/or reception.

In some embodiments the non-limiting term radio network node or simplynetwork node is used. It can refer to any type of network node thatserves UE is connected to other network nodes or network elements or anyradio node from where UE receives a signal. Examples of radio networknodes are Node B, base station (BS), multi-standard radio (MSR) nodesuch as MSR BS, eNode B, network controller, radio network controller(RNC), base station controller (BSC), relay, donor node controllingrelay, base transceiver station (BTS), access point (AP), transmissionpoints, transmission nodes, RRU, RRH, nodes in distributed antennasystem (DAS) etc.

Cloud radio access networks (RAN) can enable the implementation ofconcepts such as software-defined network (SDN) and network functionvirtualization (NFV) in 5G networks. This disclosure can facilitate ageneric channel state information framework design for a 5G network.Certain embodiments of this disclosure can comprise an SDN controllerthat can control routing of traffic within the network and between thenetwork and traffic destinations. The SDN controller can be merged withthe 5G network architecture to enable service deliveries via openapplication programming interfaces (“APIs”) and move the network coretowards an all internet protocol (“IP”), cloud based, and softwaredriven telecommunications network. The SDN controller can work with, ortake the place of policy and charging rules function (“PCRF”) networkelements so that policies such as quality of service and trafficmanagement and routing can be synchronized and managed end to end.

To meet the huge demand for data centric applications, 4G standards canbe applied 5G, also called new radio (NR) access. 5G networks cancomprise the following: data rates of several tens of megabits persecond supported for tens of thousands of users; 1 gigabit per secondcan be offered simultaneously to tens of workers on the same officefloor; several hundreds of thousands of simultaneous connections can besupported for massive sensor deployments; spectral efficiency can beenhanced compared to 4G; improved coverage; enhanced signalingefficiency; and reduced latency compared to LTE. In multicarrier systemsuch as OFDM, each subcarrier can occupy bandwidth (e.g., subcarrierspacing). If the carriers use the same bandwidth spacing, then it can beconsidered a single numerology. However, if the carriers occupydifferent bandwidth and/or spacing, then it can be considered a multiplenumerology.

A multiple (e.g., three) party communication framework for V2X canimpose a hierarchical structure in a peer-to-peer network. Inparticular, in a three-party communication framework, a given node,other than the transmitter and the receiver, can be designated tocoordinate radio resource usage. The chosen node, dubbed “localmanager”, can be responsible for the scheduling and resource allocationamong the nodes it manages. If the local manager is denoted as node-S,the transmitting nodes as node-T, the receiving node as node-R, thescheduling/resource allocation can be centralized at the node-S, whilethe data transmission is done by different nodes (node-T) in adistributed manner.

In the general framework where a local manager node-S is elected andnodes are reliably covered by node-S, the procedure can be described asfollows. The Node S can broadcast synchronization signals (e.g.,synchronization signal broadcast (SSB), transmission reception signal(TRS)) to its surrounding UEs. The broadcasted information can compriseresource pool information. Other nodes can then sync to node-S andreceive the broadcast information. When node-T has a V2X traffic datapacket, it can send a scheduling request (SR) to node-S. The SR cancomprise the following traffic types: V2X broadcast or multi-casttraffic, V2X unicast traffic that additionally indicate the receivernode, and/or cellular traffic.

Upon receiving the SR, node-S can schedule radio resources. Thescheduling decision can be transmitted as downlink control information(DCI) from node-S to node-T and node-R. The DCI can comprise theresource allocation, MCS, precoder, etc. Upon receiving the DCI, node-Tcan transmit data on the allocated radio resource while node-R receivesdata on the allocated radio resource.

As depicted in FIG. 2 , below, V2X services can comprise bothvehicle-to-infrastructure (V2I) between vehicles and gNBs or roadsideaccess point units, and vehicle-to-vehicle (V2V) communications, whichcan be over an existing cellular (Uu) interface or a sidelink (e.g., D2Dor PC5) interface.

Supporting CSI feedback and HARQ are effective tools to enhance spectrumefficiency of the communication links. Typically, CSI feedback cancomprise a CQI (Channel quality indicator), which allows the transmitterto understand what level of modulation and coding scheme (MCS) to use ina particular data packet. Generally speaking, a more aggressive MCSlevel means a higher efficiency but more sensitive to interference andnoise. On the other hand, a less aggressive MCS level means a lowerefficiency but more robust to interference and noise. Link adaption is ascheme to achieve balance between efficiency and robustness. Similarly,HARQ feedback can also help to find the best trade-off. Thus, the outerloop link adaption (OLLA) can utilize the HARQ feedback to adjust thelink adaption in finer granularity.

However, it is very expensive to have both CSI feedback and HARQ insidelink communications. As a direct communication link between devices,sidelink often works in a peer-2-peer network structure. Thus, it ishard to schedule a dedicated resource for feedback. In particular, CSIfeedback can comprise a large number of bits and become extremelycomplicated. In addition, CSI can be reported either periodically oraperidocially and the performance can be impacted by how fast the CSI isreported, which, in turn, can consume resources and degrade the sidelinkperformance.

A smart HARQ feedback can better support link adaption. In addition toHARQ feedback, which comprises feedback acknowledgements (ACK) andnegative acknowledgements (NAK) based on a decoding result, a new statefor the HARQ feedback, called “ACK+” can be introduced. ACK+ can be usedto indicate to the network that the MCS of a current data packet is tooconservative even though the UE can support a more aggressive MCS.

For example, when the UE successfully decodes a data packet (e.g.,cyclic redundancy check (CRC)=true), the UE can also estimate thedecoding quality of the data packet (e.g., UE can estimate the decodingquality based on a received DMRS SINR, the UE can estimate the decodingquality based on a data soft symbol SINR, the UE can estimate thedecoding quality based on a control channel soft symbol(s), and/or theUE can add an implementation margin in the estimation. For example, theUE can estimate the channel quality to be X, and the network canintentionally select a slightly conservative MCS to ensure that the UEpasses the test. When the estimated channel quality can support morerobust decoding with a higher MCS, the UE can report an “ACK+” back tonetwork. For example, if the estimated quality is mapped to MCS_UE, andthe scheduled MCS is MCS_scheduled, and MCS_UE>MCS_scheduled, then theUE can send an ACK+. The ACK+ can be encoded together with HARQ ACK/NAKsignaling (e.g., HARQ feedback can have two bits to indicate:NAK/ACK/ACK+). The ACK+ can also be separated, encoded, and reported inother channels. Additionally, the ACK+ can have multiple levels (e.g.,ACK+ means the UE can support one MCS higher, ACK++ means the UE cansupport two MCSs level higher, etc.). The ACK+ signaling can betransmitted as a state in a HARQ feedback channel. For example, ACK+ canequal one MCS step up, where ACK++ can equal two MCS step ups, whereinthe + can represent consecutive step ups and so forth. For sequenceselection PSFCH design, the ACK, NAK, and ACK+ can be designed as asequence. Thus, when the network receives the ACK+, the network knowsthat the corresponding data packet is transmitted with under-estimatedMCS, and the network can make MCS adjustments in addition to regularOLLA operations.

In one embodiment, described herein is a method comprising decoding, bya first wireless network device comprising a processor, a data packetreceived from a second wireless network device. In response to thedecoding, the method can comprise estimating, by the first wirelessnetwork device, a data packet decoding quality associated with a firstmodulation and coding scheme which is greater than a second modulationand encoding scheme associated with a current data packet. Additionally,in response to a value associated with the data packet decoding qualitybeing determined to greater than a threshold value, the method cancomprise transmitting, by the first wireless network device to thesecond network device, acknowledgement data indicative of a request tothe second wireless network device.

According to another embodiment, a system can facilitate decoding a datapacket received from a wireless network node device of a wirelessnetwork. In response to the decoding the data packet, the system cancomprise estimating a decoding quality associated with a potentialmodulation and coding scheme value that is greater than a current datapacket value. In response to a value representative of the decodingquality being determined to be less than a threshold value, the systemcan comprise transmitting acknowledgement plus data indicative of aquality lapse between the decoding quality and the channel quality.

According to yet another embodiment, described herein is amachine-readable storage medium that can perform the operationscomprising facilitating decoding a data packet received from a wirelessnetwork node device of a wireless network. In response to the decodingthe data packet, the machine-readable storage medium can perform theoperations comprising facilitating estimating a first value associatedwith a decoding quality of the decoding of the data packet. In responseto the first value being determined to be less than a second valueassociated with a channel quality of the wireless network, themachine-readable storage medium can perform the operations comprisingfacilitating transmitting acknowledgement plus data indicative of alapse in quality between the decoding quality and the channel quality.

These and other embodiments or implementations are described in moredetail below with reference to the drawings.

Referring now to FIG. 1 , illustrated is an example wirelesscommunication system 100 in accordance with various aspects andembodiments of the subject disclosure. In one or more embodiments,system 100 can comprise one or more user equipment UEs 102, 104. Thenon-limiting term user equipment can refer to any type of device thatcan communicate with a network node in a cellular or mobilecommunication system. A UE can have one or more antenna panels havingvertical and horizontal elements. Examples of a UE comprise a targetdevice, device to device (D2D) UE, machine type UE or UE capable ofmachine to machine (M2M) communications, personal digital assistant(PDA), tablet, mobile terminals, smart phone, laptop mounted equipment(LME), universal serial bus (USB) dongles enabled for mobilecommunications, a computer having mobile capabilities, a mobile devicesuch as cellular phone, a laptop having laptop embedded equipment (LEE,such as a mobile broadband adapter), a tablet computer having a mobilebroadband adapter, a wearable device, a virtual reality (VR) device, aheads-up display (HUD) device, a smart car, a machine-type communication(MTC) device, and the like. User equipment UE 102 can also comprise IOTdevices that communicate wirelessly.

In various embodiments, system 100 is or comprises a wirelesscommunication network serviced by one or more wireless communicationnetwork providers. In example embodiments, a UE 102 can becommunicatively coupled to the wireless communication network via anetwork node 106. The network node (e.g., network node device) cancommunicate with user equipment (UE), thus providing connectivitybetween the UE and the wider cellular network. The UE 102 can sendtransmission type recommendation data to the network node 106. Thetransmission type recommendation data can comprise a recommendation totransmit data via a closed loop MIMO mode and/or a rank-1 precoder mode.

A network node can have a cabinet and other protected enclosures, anantenna mast, and multiple antennas for performing various transmissionoperations (e.g., MIMO operations). Network nodes can serve severalcells, also called sectors, depending on the configuration and type ofantenna. In example embodiments, the UE 102 can send and/or receivecommunication data via a wireless link to the network node 106. Thedashed arrow lines from the network node 106 to the UE 102 representdownlink (DL) communications and the solid arrow lines from the UE 102to the network nodes 106 represents an uplink (UL) communication.

System 100 can further include one or more communication serviceprovider networks 108 that facilitate providing wireless communicationservices to various UEs, including UE 102, via the network node 106and/or various additional network devices (not shown) included in theone or more communication service provider networks 108. The one or morecommunication service provider networks 108 can include various types ofdisparate networks, including but not limited to: cellular networks,femto networks, picocell networks, microcell networks, internet protocol(IP) networks Wi-Fi service networks, broadband service network,enterprise networks, cloud based networks, and the like. For example, inat least one implementation, system 100 can be or include a large scalewireless communication network that spans various geographic areas.According to this implementation, the one or more communication serviceprovider networks 108 can be or include the wireless communicationnetwork and/or various additional devices and components of the wirelesscommunication network (e.g., additional network devices and cell,additional UEs, network server devices, etc.). The network node 106 canbe connected to the one or more communication service provider networks108 via one or more backhaul links 108. For example, the one or morebackhaul links 108 can comprise wired link components, such as a T1/E1phone line, a digital subscriber line (DSL) (e.g., either synchronous orasynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, acoaxial cable, and the like. The one or more backhaul links 108 can alsoinclude wireless link components, such as but not limited to,line-of-sight (LOS) or non-LOS links which can include terrestrialair-interfaces or deep space links (e.g., satellite communication linksfor navigation).

Wireless communication system 100 can employ various cellular systems,technologies, and modulation modes to facilitate wireless radiocommunications between devices (e.g., the UE 102 and the network node106). While example embodiments might be described for 5G new radio (NR)systems, the embodiments can be applicable to any radio accesstechnology (RAT) or multi-RAT system where the UE operates usingmultiple carriers e.g., LTE FDD/TDD, GSM/GERAN, CDMA2000 etc.

For example, system 100 can operate in accordance with global system formobile communications (GSM), universal mobile telecommunications service(UMTS), long term evolution (LTE), LTE frequency division duplexing (LTEFDD, LTE time division duplexing (TDD), high speed packet access (HSPA),code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000,time division multiple access (TDMA), frequency division multiple access(FDMA), multi-carrier code division multiple access (MC-CDMA),single-carrier code division multiple access (SC-CDMA), single-carrierFDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM),discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrierFDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tailDFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency divisionmultiplexing (GFDM), fixed mobile convergence (FMC), universal fixedmobile convergence (UFMC), unique word OFDM (UW-OFDM), unique wordDFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM,resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However,various features and functionalities of system 100 are particularlydescribed wherein the devices (e.g., the UEs 102 and the network device106) of system 100 are configured to communicate wireless signals usingone or more multi carrier modulation schemes, wherein data symbols canbe transmitted simultaneously over multiple frequency subcarriers (e.g.,OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments areapplicable to single carrier as well as to multicarrier (MC) or carrieraggregation (CA) operation of the UE. The term carrier aggregation (CA)is also called (e.g., interchangeably called) “multi-carrier system”,“multi-cell operation”, “multi-carrier operation”, “multi-carrier”transmission and/or reception. Note that some embodiments are alsoapplicable for Multi RAB (radio bearers) on some carriers (that is dataplus speech is simultaneously scheduled).

In various embodiments, system 100 can be configured to provide andemploy 5G wireless networking features and functionalities. 5G wirelesscommunication networks are expected to fulfill the demand ofexponentially increasing data traffic and to allow people and machinesto enjoy gigabit data rates with virtually zero latency. Compared to 4G,5G supports more diverse traffic scenarios. For example, in addition tothe various types of data communication between conventional UEs (e.g.,phones, smartphones, tablets, PCs, televisions, Internet enabledtelevisions, etc.) supported by 4G networks, 5G networks can be employedto support data communication between smart cars in association withdriverless car environments, as well as machine type communications(MTCs). Considering the drastic different communication needs of thesedifferent traffic scenarios, the ability to dynamically configurewaveform parameters based on traffic scenarios while retaining thebenefits of multi carrier modulation schemes (e.g., OFDM and relatedschemes) can provide a significant contribution to the highspeed/capacity and low latency demands of 5G networks. With waveformsthat split the bandwidth into several sub-bands, different types ofservices can be accommodated in different sub-bands with the mostsuitable waveform and numerology, leading to an improved spectrumutilization for 5G networks.

To meet the demand for data centric applications, features of proposed5G networks may comprise: increased peak bit rate (e.g., 20 Gbps),larger data volume per unit area (e.g., high system spectralefficiency—for example about 3.5 times that of spectral efficiency oflong term evolution (LTE) systems), high capacity that allows moredevice connectivity both concurrently and instantaneously, lowerbattery/power consumption (which reduces energy and consumption costs),better connectivity regardless of the geographic region in which a useris located, a larger numbers of devices, lower infrastructuraldevelopment costs, and higher reliability of the communications. Thus,5G networks may allow for: data rates of several tens of megabits persecond should be supported for tens of thousands of users, 1 gigabit persecond to be offered simultaneously to tens of workers on the sameoffice floor, for example; several hundreds of thousands of simultaneousconnections to be supported for massive sensor deployments; improvedcoverage, enhanced signaling efficiency; reduced latency compared toLTE.

The upcoming 5G access network may utilize higher frequencies (e.g., >6GHz) to aid in increasing capacity. Currently, much of the millimeterwave (mmWave) spectrum, the band of spectrum between 30 gigahertz (Ghz)and 300 Ghz is underutilized. The millimeter waves have shorterwavelengths that range from 10 millimeters to 1 millimeter, and thesemmWave signals experience severe path loss, penetration loss, andfading. However, the shorter wavelength at mmWave frequencies alsoallows more antennas to be packed in the same physical dimension, whichallows for large-scale spatial multiplexing and highly directionalbeamforming.

Performance can be improved if both the transmitter and the receiver areequipped with multiple antennas. Multi-antenna techniques cansignificantly increase the data rates and reliability of a wirelesscommunication system. The use of multiple input multiple output (MIMO)techniques, which was introduced in the third-generation partnershipproject (3GPP) and has been in use (including with LTE), is amulti-antenna technique that can improve the spectral efficiency oftransmissions, thereby significantly boosting the overall data carryingcapacity of wireless systems. The use of multiple-input multiple-output(MIMO) techniques can improve mmWave communications, and has been widelyrecognized a potentially important component for access networksoperating in higher frequencies. MIMO can be used for achievingdiversity gain, spatial multiplexing gain and beamforming gain. Forthese reasons, MIMO systems are an important part of the 3rd and 4thgeneration wireless systems, and are planned for use in 5G systems.

As depicted in FIG. 2 , V2X services can comprise bothvehicle-to-infrastructure (V2I) communication between vehicles 202 ₄ 202₁ and gNB 106 or roadside access point units, and vehicle-to-vehicle(V2V) 202 ₁, 202 ₂, 202 ₃, 202 ₄ communications, which can be over anexisting cellular (Uu) interface or a sidelink (e.g., D2D or PC5)interface.

Thus, the communication can be a predefinedstructure as with a conventional network or simply an ad hoccommunication between at least two devices.

Wi-Fi, or Wireless Fidelity, allows connection to the Internet from acouch at home, in a hotel room, or a conference room at work, withoutwires. Wi-Fi is a wireless technology similar to that used in a cellphone that enables such devices, e.g., computers, to send and receivedata indoors and out; anywhere within the range of a base station. Wi-Finetworks use radio technologies called IEEE 802.11 (a, b, g, etc.) toprovide secure, reliable, fast wireless connectivity. A Wi-Fi networkcan be used to connect computers to each other, to the Internet, and towired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networksoperate in the unlicensed 2.4 and 5 GHz radio bands, at an 7 Mbps(802.11a) or 54 Mbps (802.11b) data rate, for example, or with productsthat contain both bands (dual band), so the networks can providereal-world performance similar to the basic 16BaseT wired Ethernetnetworks used in many offices.

An aspect of 5G, which differentiates from previous 4G systems, is theuse of NR. NR architecture can be designed to support multipledeployment cases for independent configuration of resources used forRACH procedures. Since the NR can provide additional services than thoseprovided by LTE, efficiencies can be generated by leveraging the prosand cons of LTE and NR to facilitate the interplay between LTE and NR,as discussed herein.
